FILLING-POSITIONING DEVICE FOR LOOMS.

Specification of Letters Patent.

Patented Dec. 29, 1914:.

Application filed December 22, 1913. Serial No. 808,113.

To all whom it may concern Be it known that I, FRANK D. HERRING, acitizen of the United States, residing at Lindale, county of Floyd,State of Georgia, have invented an Improvement in Filling- PositioningDevices for Looms, of which the following description, in connectionwith the accompanying drawing, is a specification, like characters onthe drawing representing like parts.

It is common in automatic filling replenishing looms to provide meansfor parting or severing the filling close to the filling carriercontaining the filling supply to be abandoned at the time a change offilling carriers is effected. Such filling parting means are frequentlyattached to and moved with the shuttle feeler which prevents fillingtransfer taking place when a shuttle has been improperly boxed at thetransfer end of the loom. Such filling parting means and such specificfilling parting means carried by the shuttle feeler are disclosed in thepatent to Draper No. 683,423, granted September 24, 1901, in connectionwith the well known Northrop type of automatic filling replenishingloom. It sometimes happens that the filling trailing behind thefillingcarrier from its position at the transfer end of the loom doesnot get into the path or field of operation of the thread parting means,and hence is not severed. This may be due to the shuttle reboundingslightly or sufiiciently to lower the run of filling onto or adjacent tothe bottom of the raceway or to other causes. When the failure to partthe filling takes place an undue strain is placed upon the pick lastbeaten in, causing liability to injury to the cloth, and the brokenfilling end left after transfer takes place will not be cut by the usualtemple thread cutter at the selvage, but will be liable to snap back orbe worked into the shed and woven in, causing an imperfection.

It is the object of the present invention to provide a means forpositively insuring the position of the filling to be parted in thefield of operation of the parting means, and to insure the actuation ofthe filling positioning means upon the call for filling replenishment.

The object and nature of the invention will appear more fully from theaccompanying description and drawings, and will be pointed out in theappended claims.

The drawings represent so much of the mechanism of an automatic weftreplenishing loom of the Northrop type as is necessary to a disclosureof the present invention, together with the parts forming the preferredform of this invention applied thereto.

In the drawings: Figure 1 is a top plan view, broken out at each sideand centrally, of a sufiicient portion of an automatic fillingreplenishing loom with the preferred embodiment of this inventionapplied thereto; Fig. 2 is a front elevation of a portion of the layshowing the parts directly concerned with the positioning of thefilling; Fig. 3 is a view in transverse cross-section taken on the linecc-m Fig. 1.

The general construction and operation of the automatic fillingreplenishing loom herein illustrated with the exception of the partsrequired to embody the present invention is familiar and is disclosed ina number of patents, such as that to C. H. Draper No. 683,423 abovereferred to, or that to Rhoades No. 1,020,622 granted March 19, 1912.

The lay 1 having the shuttle boxes 2 at the feeling end, and 3 at thetransfer end, the hopper or feeder 4 containing a supply of full fillingcarriers such as the bobbins 5, the breast beam 6, weft fork 7, thefilling feeler 8, the transferrer arm 9, and the connections by whichupon the indication of a predetermined degree of exhaustion of therunning filling by the feeler 8 the transferrer arm 9 is operated totransfer the filling as by forcing a fresh bobbin from the hopper intothe shuttle therebeneath and ejecting the spent bobbin, are all familiarand need no detailed description. It will be remembered, however, thatupon the call for filling replenishment as by the indication of apredetermined degree of exhaustion in the running filling by the feeler8 a controller rock shaft 10 is rocked to effect the operation andpositioning of the parts necessary to secure the transfer, and in thepreferred form of the invention herein illustrated this controlling rockshaft is made use of, preferably through an arm already connectedthereto, for the support and operation of the actuating elements in thefilling positioning means.

The loom is shown as provided with a suitable filling parting means andthe ordinary thread, parting means carried by the ordinary shuttlefeeler, such as shown in the. patents previously referred to isillustrated. The shuttle feeler shown at 11 comprises a swinging armpivoted on the loom frame at 12, and adapted to swing into position sothat as the lay beats up it will feel for the boxed shuttle immediatelyin the, rear of its proper position so that if the shuttle is improperlyboxed the shuttle feeler will strike the shuttle and through the usualconnections prevent transfer taking place. The shuttle feeler is movedinto operative position by the usual slotted arm 13 engaging the lug 14:connected with the dog 15 which dog is thrown into the path of thehunter 1.6

on the lay upon the call for filling replenishment. The thread partingmeans may also be of any suitable construction and operation, and isherein illustrated as of usual form and is herein illustrated at 17carried and supported by the shuttle feeler 11. It is shown as the sameconstruction as illustrated in the patents above referred to, andcomprises not only a filling parter but a filling clamp to seize andhold the end of the filling and carry it back into the path of the.usual temple thread cutter, not herein shown. In this type. of mechanismthe controller rock shaft 10 is; usually provided with and fast upon itan arm 18 connected to one end of a strong spring 19 which at its lowerend is secured to the loom frame, said spring holding the arm in theposition shown in Fig. 4 upon a pin 20 on the shuttle feeler support 11and eccentric to the fulcrum or pivot 12 thereon, thus maintaining theshuttle feeler and thread parting means carried thereby in the normalorinoperative position, shown in Fig. 4. In addition, to these familiarfeatures of construction the form of the invention herein illustrated inconnection with this form of 100m provides a vieldingly depressed lifterdevice mounted on the lay adjacent the shuttle-box in Whi ch transfertakes place and normally flush with or below the bottom of the racewayand a striker carried by the breast beam normally out of the path ofthis lifter device, but moved upon the call for filling replenishmentinto the path thereof, so that when the lay heats up the lifter devicewill be elevated to a position to hold the filling accurately in thepath of the filling parting means.

A bracket 21 is fastened to the face of the lay and is provided with avertical bearing 22 and a depending guide 23. The lifter devicecomprises a vertically movable standard 24 mounted to slide in thebearing 22 and provided at its lower end with an arm 25 guided in a slotin the guide 23. spring 26 between the arm 25 and the lay serves tomaintain the standard in lowermost position. At its upper end the standand is formed into orhas-eonneoted there-.

With an arm 27 projecting across the raceway immediately behind theposition which the shuttle occupies when boxed. In the constructionshown the standard 24 is bent to run parallel at 28 with the lay andthen bent rearwardly to cross the raceway. The portion 28 is in twoparts hinged or pivoted together and provided with a light spring 29holding the parts in normal position, but

enabling the arm 27 to be swung downwardly by a slight pressure. Theraceway is cut away beneath the arm 27 so that the arm lies flush withor below the level of the raceway so as not to interfere with themovement of the shuttle back and forth on the raceway. These partsoccupy normally the position shown in Fig. 2 being entirely inactive andin no way interfering with the usual operation of the loom parts.

A striker is carried by the breast beam opposite the arm 25 and broughtinto the path thereof when it is desired to effect the operation of thepositioning means. This haustion of the filling has been indicated bythe feeler 8 and the controller rock shaft 10 has been revolved toelevate the arm 18, the striker30 will be carried therewith into aposition so that when the laybeats up the arm 25 will ride up the camsurface 32 el'evating the arm 27 and carrying with it the filling, thuspositioning and holding the filling accurately in the path of theparting means. The arm 27 is vertically adjustable as by means of theset screw 33 so that the position of the filling may be regulated inaccordance with the path or field of operation of the thread partingmeans. Since the arm 27 is not elevated until the lay beats up into. thepath of the striker 30 the shuttle has already passed over the arm 27 inits de-. pressed position and enters the box at the, transfer end. Ifthe shuttle should slightly rebound or in any way be thrown back afterpassing over the arm 27 provision is madev for preventing injury to theparts by the.

spring connection of the portion 28 of the-- tion lying beneath theplane of the raceway, and when the standard is in its operative positionacting to position and holdthe filling in the path of the parting means,but yielding if struck by the shuttle, and means carried by the lay formoving said standard into operative position upon the call for fillingreplenishment.

2. In an automatic weft replenishing loom a shuttle feeler movablymounted on the loom frame and when moved into operative position actingto feel for and detect, when the lay beats up, an improperly boxedshuttle at the transfer end of the loom, thread parting means carried bysaid shuttle feeler topart the filling in the rear of the shuttle whenthe lay heats up, filling positioning means mounted on the lay andnormally below the raceway and movable upon the call for fillingreplenishment to raise and: position the filling in the path of saidparting means.

3. In an automatic weft replenishing loom a shuttle feeler movablymounted on the Copies of this patent may be obtained for loom frame andwhen moved into operative position acting to feel for and detect whenthe lay beats up an improperly boxed shuttle at the transfer end of theloom, thread parting means carried by said shuttle feeler to part thefilling in the rear of the shuttle when the lay beats up, a yieldinglydepressed lifter device mounted on the lay and normally flush with orbelow the bottom of the raceway, a striker normally out of the path ofsaid lifter device, and means actuated upon the call for fillingreplenishment to move the striker into the path of the lifter device asthe lay beats up, thus to raise the lifter device to position and holdthe filling in the path of the parting means.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
